A failure occurred while executing org.jetbrains.kotlin.gradle.internal.KaptExecution

Question

All of sudden I start getting this error, and I am not getting idea why if anyone just let me know where this error is, will be enough helpful. As much I am able to get is t

Answer 1

In my case I have changed globally one variable UserManager to NetWorkManager and everywhere where there were UserManager classes they turned to be NetworkManager.

Because I'm using Hilt, I had to build the project again.

I cleaned the Project and Kotlin showed where the errors were.

Answer 2

Interestingly, I was getting this error because I added the description of the Retrofit. Be careful not to confuse the description of Room and Retrofit.

Answer 3

in some cases it may help gradle.properties

kapt.include.compile.classpath=true

Answer 4

The way to find out what the underlying issue is, is to run the following command :

./gradlew assembleDebug --stacktrace

Answer 5

In my case, I used room and one of my databasDao methods has an unused parameter and unfortunately android studio doesn't warn me correctly

Answer 6

I had the same problem. Let me walk you through the example on how I ended up to the problem and the way I resolved it perhaps you can get a bigger picture.

Before resolving

@Entity(tableName = "modules")
data class Module
(
    @PrimaryKey val id: Int,
    val name: String
)

@Entity(tableName = "sessions")
data class Session
(
    @PrimaryKey(autoGenerate = true) var id: Int,
    @ColumnInfo(name = "module_id") val moduleId: Int,
    @ColumnInfo(name = "start_time") val startTime: String,
    @ColumnInfo(name = "end_time") val endTime: String
)

data class ModuleSession
(
    @Embedded val module: Module,
    @Relation(
        parentColumn = "id",
        entityColumn = "module_id"
    )
    val sessions: List<Session>,
    @ColumnInfo(name = "is_updated") val isUpdated: Boolean = false // The problem
)

In the DAO

@Transaction
@Query("SELECT * FROM modules")
abstract suspend fun getModuleSession(): List<ModuleSession>

The error I got was

A failure occurred while executing org.jetbrains.kotlin.gradle.internal.KaptExecution

So I dug deeper and found the below message

The columns returned by the query does not have the fields [isUpdated] in com.gmanix.oncampusprototype.Persistence.ModuleSession even though they are annotated as non-null or primitive. Columns returned by the query: [id,name]
    public abstract java.lang.Object getModuleSession(@org.jetbrains.annotations.NotNull()

I removed the field IsUpdated from the POJO ModuleSession and added it to the session table

After changes

@Entity(tableName = "sessions")
data class Session
(
    @PrimaryKey(autoGenerate = true) var id: Int,
    @ColumnInfo(name = "module_id") val moduleId: Int,
    @ColumnInfo(name = "start_time") val startTime: String,
    @ColumnInfo(name = "end_time") val endTime: String,
    @ColumnInfo(name = "is_updated") val isUpdated: Boolean = false
)

data class ModuleSession
(
    @Embedded val module: Module,
    @Relation(
        parentColumn = "id",
        entityColumn = "module_id"
    )
    val sessions: List<Session>
)

On the other hand crosscheck if there is any field on the SELECT statement that is a suspect causing issues or you can annotate it with @Ignore

However you can post your code if you're still not comfortable.

I hope that might help
